AI Technical Summary

Benefits of technology

The present invention is about lighting fixtures that can be customized to control the distribution and intensity of light in a specific area. This allows for greater flexibility and control over lighting than some current fixtures. The invention can be applied to LEDs or other solid state light sources, as well as other fixtures with multiple light sources. The technical effect of the invention is improved customization and control over lighting in specific areas.

Problems solved by technology

One disadvantage to such current art approaches is that the designed optics are only useful in producing a single beam type; they must be modified or replaced if a different beam type is desired.
Additionally, such fixtures afford little flexibility; a type II beam pattern (as defined by IES) may be sufficient to illuminate a target area but if the target area changes (e.g., the area to be illuminated is increased, the target area is moved), or the lighting needs change (e.g., spill light needs to be eliminated, glare needs to be controlled), the beam type may no longer be appropriate for the application.

[0035]B. Exemplary Method and Apparatus Embodiment I

[0036]A more specific exemplary embodiment, utilizing aspects of the generalized example described above, will now be described. FIG. 2 illustrates one possible lighting fixture 10 which houses multiple LEDs and comprises an aluminum housing 14, a removable panel 13 for access to the power regulating devices associated with the LEDs (which are well known in the art of lighting), a removable lens 15 for access to the LEDs and associated optics, and an adjustable mounting knuckle 12 for mounting lighting fixture 10 to a pole 11 or other structure. As described in the incorporated-by-reference parent patent applications, lens 15 may further comprise an anti-reflective coating which, as is well known in the art of lighting, may allow for a variety of angles of incidence up from normal.

Abstract

Disclosed herein are apparatus, method, and system for producing a customizable composite beam from a plurality of solid state light sources. Each light source is associated with individually adjustable fixture components which allow for a variety of lighting needs to be addressed. The composite beam is a collective of the beam projected from each adjustable component / light source combination; each individual beam being of customized shape or standard shape.
